Embodiment Construction

[0036] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0037] A method of using multiple boards to protect HQoS, used to protect the HQoS configuration strategy of Ethernet convergence layer equipment. The equipment, such as figure 1 As shown, the main board card (main business processing board) and multiple backup boards (standby business processing board) are included at the same time, and the service interface card is connected to multiple business processing boards at the same time through the connector. When the service processing board is in a normal working state, the connector will follow the default access relationship, and the message en...

Abstract

The invention discloses a method and device for protecting HQoS by using multiple boards. The method of the invention sequentially encodes VOQ-IDs for all business segments through the main board, and then synchronizes the allocated VOQ-IDs together with HQoS configuration information to all standby boards All business boards apply for VOQ resources and complete HQoS configuration. When the main board fails, the faulty main board is taken offline, port protection is switched, and the standby board is updated to the VOQ‑ID of the offline faulty main board and elected as the main board. . The device of the present invention corresponds to the method. When the main board fails, the present invention only needs to change the NODE-ID bit in the VOQ-ID to realize the rapid protection switching of the traffic to the standby board, which is simple to implement and strong in operability.

Description

Technical field [0001] The present invention relates to the field of network communication, and more specifically to a method and device for protecting HQoS using multiple boards. Background technique [0002] With the development of technology and the times, Ethernet technology has increasingly become an important technical means for social production and office. With the rapid growth of smart terminal holdings, the mobile Internet industry has become increasingly mature. The development of wireless networks to ALL IP (full network IP) requires a large capacity of the convergence layer equipment and a fast service response mechanism to ensure that the service is never interrupted and highly reliable. [0003] Traditional Ethernet convergence layer equipment is usually equipped with one service processing board and multiple service interface cards, which has certain security problems. When the service board of the convergence layer equipment fails, all services connected to it wi...
